CORN-HUSKING ROLLERS.

Specification of Letters Patent.

Application filed March 28, 1912.

Patented June 25, 1912.

Serial No. 686,941.

To all whom t may concern:

Be it known that I, BARNEY GRONKE, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Corn-Husking Rollers, of which the following is a specification.

My invention relates to corn husking rollers that are driven in opposite directions in a manner to engage with the husks of the ears of corn and strip them therefrom. It is usual to provide rollers having some particular form carrying husk engaging teeth that engage the husks more or less aggressively. If too aggressive in their action the result will be that a large amount of corn will be shelled from the ears, and if less aggressive, the ears will be only partly husked; the object of my invention being to provide a construction of rollers that will successfully engage the husks and strip them from the ears without shelling the corn. I attain this object by means of the mechanism illustrated by the accompanying drawings, in which- Figure l represents a top plan view 'of a pair of husking rollers having my invention embodied in the construction thereof; Fig. 2 is across section along line A-B of Fig. 1 Fig. 3 is a cross section of Fig. l along line B-C; and Eig. 4 is a cross section of the coacting rollers, partly broken away and designed to illustrate the rollers in a different angular relation.

The same reference characters designate like parts throughout the several views.

The coacting rollers are journaled in bearings l secured to a frame member 2 and having intermeshing pinions 3 secured to the ends thereof whereby motion is imparted thereto in opposite directions. The opposite ends of the rollers are not shown in full, but may be journaled upon the frame of the machine in any preferred manner.

One of the rolls, designated by reference character 4, is cylindrical in form and provided with two rows of pockets 5, spaced apart in the direction of the length of the roll in lines parallel with the axis thereof, the two rows of pockets being arranged in diametrical relation upon the periphery of the roll and having the pockets in one row alternating with those in the opposite row. The pockets are elongated in a circumferential direction and gradually increase in depth along a straight line in a direction opposite to that in which the roll rotates and have the end walls and side walls thereof curved upward from the bottom toward the periphery of the roll. The roll is also pro vided with two rows of radially projecting pins 6, spaced apart in the direction of the length of the roll in lines parallel with the axis thereof and in diametrical relation, the rows being equidistant from and intermediate the two rows of pockets and having the pins equidistant from circumferential lines drawn through the pockets. The coacting roll 7 is cylindrical in form in lines arranged in a longitudinal direction parallel with the axis of the roll throughout part of the periphery thereof. The cylindrical portions are designated by the reference-character 8 and terminate `in depressed flattened portions 9 arranged upon opposite sides of the roll at 90o angles from each other, and with the flattened portions upon opposite sides of the roll in parallel relation. The flattened portions are not chordal throughout the whole width thereof but terminate in outwardly curved portions 10 that terminate in the cylindrical portions at the sides thereof in the direction of the rotation of the roll.

ll represents pockets in two of the flattened portions that are spaced apart in the direction of the length of the roll and in alternating relation upon the oppositely disposed flattened portions and with the bottoms thereof upon a chordal line beginning at the junction of the curved portions 10 with the flattened portions and curving upward at the opposite ends thereof terminate in the cylindrical portions beyond the flattened portions, the deepest part of the pockets being at the side of the flattened portions opposite to the direction of rotation of the roll and registering with the pins 6 upon the opposing roll 4. There are two rows of pins l2 upon roll 7, arranged in lines parallel with the axis of the roll and upon the flattened portions that are not provided with pockets, and near the side thereof opposite to the direction of rotation of the roll, that register with pockets in the opposing roll 4 at the deepest portion thereof. The pins 12 are arranged upon lines at an angle with radial lines and incline outward in the direction of rotation of the roll.

In corn husking machines the husking rollers are commonly inclined downward in the direction of the length thereof from the ear receiving ends toward the delivery ends thereof, and the husls are removed from the ears as the latter move toward the delivery ends. rIhe greater portion ofthe husks are removed from the ears as soon as they are engaged by the receiving ends of the rolls, and I have found it desirable to construct the rolls in a manner whereby they will operate in a less aggressive manner in removing the husks', and thus have a less tendency to shell the corn as the ears approach the delivery ends of the rolls, and for that purpose I provide the roll 7 with a series of transversely arranged raised portions 13 upon a portion of the delivery end and upon each of the flattened portions thereof. Those upon the flattened sides having' the pockets ll therein are arranged upon i the sides of the pockets in the direction of the receiving end of the roll with the sides thereof adjacent the pockets forming a part of the side wall of the latter, and those upon the other two flattened sides of the roll arranged thereon intermediate therpins 12.

lVhat I claim as my invention, and desire to secure by Letters Patent, is:

l. A pair of coacting corn huslcing rolls including, in combination, one cylindrical roll having two rows of pockets spaced apart in the direction of the length of said roll, upon opposite sides thereof and in lines parallel with the axis thereof, said pockets being arranged in alternating relation in the two rows and having a gradually increasing depth along a chordal line in a direction opposite that of the rotation of said roll, and two rows of pins extending beyond the periphery of said roll, spaced apart in the direction of the length of said roll and in lines Lparallel with the axis thereof and intermediate said rows of pockets, a companion roll having two pairs of oppositely disposed flattened portions arranged longitudinally thereon, o-ne of said pairs being provided with pins that register with the pockets in the companion roll and the remaining pair registering with the pins carried by the companion roll.

2. A pair of coacting corn husling rolls including, in combination, one cylindrical roll having two rows of pockets spaced apart in the direction of the length of said roll, upon opposite sides thereof and in lines parallel with the axis thereof, said pockets being arranged in alternating relation upon the two rows and having a gradually increasing depth along a chordal line in a direction opposite that of the rotation of said roll, and two rows of pins extending beyond the periphery o-f said roll, spaced apart in the direction of the length of said roll and in lines parallel with the axis thereof and intermediate said rows of pockets, a companion roll having two pairs of oppositely disposed iiattened portions arranged longit-udinally thereon equidistant apart circumferentially, one of said pairs being provided wit-h pins that register with the deeper portions of the pockets lin the companion roll, and the remaining pair having circumferentially arranged pockets adapted to register with the pins upon the companion roll.

3. A pair of coacting corn husling rolls including, in combination, one cylindrical roll having two rows of pockets elongated circumferentially and spaced apart in the direction of the length of said roll, upon opposite sides thereof and in lines parallel with the axis thereof, said pockets being arranged in alternating relation upon the two rows and having a gradually increasing depth along a chordal line in a direction opposite that of the rotation of said roll, and two rows of pins extending beyond the periphery of said roll spaced apart in the direction of the length thereof and in lines parallel with the axis thereof and intermediate said rows of pockets, a companion roll having two pairs of oppositely disposed flattened portions arranged, longitudinally thereon equidistant apart circumferentially, one of said pairs being provided with pins that register with the pockets in the cornpanion roll and the remaining pair having circumferentially arranged pockets adapted to register with the pins upon the companion roll, said flattened portions having a series of raised portions adjacent a number of. said pockets and between the pins at the de-V livery end of said roll.
